What It Is

Mathplane (Mathplane Express) is a website focused on math help, tutoring materials, practice worksheets, and fun math content. The site’s main content indicates that its resources are intended for students, teachers, tutors, and general visitors, offering free math notes, practice tests, comics, and other math materials. It also presents information about founder Lance Friedman’s offline math tutoring services in the North Shore area of Chicago.

Core Content and Format

In terms of subject coverage, Mathplane includes pre-algebra, algebra, geometry, trigonometry, Algebra 2, calculus, as well as ACT/SAT math and standardized test prep. Each section is organized using “Gate” and “Flight List” structures. For example, the algebra section includes exponents and radicals, inequalities, linear equations/systems of equations, polynomials, and more; the calculus section covers limits, derivatives, integrals, AP-related review, and other topics. The learning format is mainly self-study resources on the website, including notes, example problems, worksheets, and test materials. There is no clear indication of video courses, live classes, a learning progress system, or automatic grading.

Pricing and Certificates

The website clearly states that Math Plane is a place for users to find free notes, practice tests, comics, and similar content, and says it is “not intended to make money.” However, it does accept donations for website maintenance, hosting, improvements, and related costs. There are also preview and purchase links for the memoir Bring Oscar, as well as an entry point for local tutoring services, but the main text does not disclose specific prices. No accreditation, course completion certificates, or credit information was found.

Pros and Cons

Its strengths are that the resources are free, cover a wide range of topics, and are suitable for printing and non-commercial classroom use. The founder has a background in mathematics and more than 10 years of tutoring experience, which adds credibility. For teachers and tutors, it can serve as a supplementary source for handouts, practice exercises, and test prep materials. Its limitations are that the site is more like a resource library than a structured online course platform; it lacks interactive explanations, problem feedback, learning path tracking, and service guarantees. The content also includes pet travel, memoir-related material, and other non-education topics, making the educational product positioning feel somewhat scattered.

Who It’s For and Access from China

It is suitable for middle and high school students with strong English skills, ACT/SAT test takers, teachers, and tutors who want to fill knowledge gaps, print practice materials, or create supplemental classroom resources. Users who need Chinese-language courses, systematic instruction, certificates, or online Q&A may need to choose another platform. Access from mainland China cannot be determined based on the available text and is therefore marked as unknown.
